Abstract (en)
In microcapsules with walls obtained by polyaddition from polyisocyanates and polyamines in aqueous emulsion, the emulsifier used is protein hydrolysate. An Independent claim is also included for the production of microcapsules by: (1) emulsifying (a) an oil phase, containing an organic, water-immiscible solvent that is inert towards isocyanates, the substance to be encapsulated and polyisocyanate, in (b) an aqueous phase containing protein hydrolysate as emulsifier and optionally additives; and (2) adding a crosslinker (polyamine) with amino (NH2) groups that can react with isocyanate groups.
